History of Calhoun County
Calhoun County was settled by Americans during the very early 19th century, and officially organized in 1825. It was named for Vice President John C. Calhoun. The southern side of the county, covered in thick forest, was untouched until the population began to expand in the late 1840s with the arrival of German immigrants. Land was cleared for farming, exporting lumber, and constructing spacious log barns, typically 200 square feet (19 m2) in size, which were a "trademark of successful German farmers." The territory was originally settled by indigenous people who occupied the resource-rich river valleys near waterways. The remains of their occupation have provided some of the most valuable archaeological information in the country. The county's archaeological record chronicles more than 10,000 years of continuous human occupation by Native Americans.
